Abstract
We redescribe two of the valid species of the Afrotropical galerucine genus Pimentelia Laboissière, 1939. This group forms a distinct monophyletic group, characterized by several external and genitalic characters. It is closer related to Galerudolphia Hincks, 1949 and Neobarombiella Bolz & Wagner, 1912. The revision is based on the examination of 30 specimens from continental Africa, and contains two valid species: the type of the genus, Pimentelia kuanduensis Laboissière, 1939, and Pimentelia maculata (Jacoby, 1885) comb. nov. (= Sermyloides unifasciata Jacoby, 1900 syn. nov.). A further species originally described, Pimentelia ochracea Laboissière, 1939 is unknown to us, type material could not be found. Another species, Pimentelia hertigi (Laboissière, 1931), has to be transferred to another group since external characters show that it is not closely related to Pimentelia and does not belong to this genus. Pimentelia is described in detail, redescriptions are provided for the two known species, including figures of external and genitalic characters, and distribution maps. A key is provided to facilitate species identification.
